Scientists reveal how cosignaling receptors dually regulate T cell activation via phase separation
Previous studies have shown that upon antigen stimulation, the T cell receptor (TCR) undergoes phase separation with the kinase Lck to mediate rapid T cell activation. However, the manner in which costimulating receptors regulate this process has remained unclear.
